No one was injured when the gunman fired a single round into the air. Though police said yesterday they do not believe the crime is connected to the armed robbery of a taxi driver in East Windsor in a cab that left Hightstown last month, authorities are unsure if the suspects are local.

“We’re investigating that to see what connections to the area,” Police Director James LeTellier said.

The suspects fled the area without taking the victim’s car.

Witnesses and the victim told police the robbery attempt happened outside the Deerfield Apartment complex off Westerly Road about 8:30 p.m. He was approached by two men, one of them armed with a handgun, who tried to steal the car, according to police.

When the victim ran, the armed suspect fired the shot in the air. Both suspects then left, possibly behind the wheel of a black car of unknown make or model they had driven to the complex.

The suspect who carried the silver handgun is described as a black male in his late 20s or early 30s, 6 feet tall, stocky build, with a chin-strap style beard or goatee, short dark hair, and a tribal-style tattoo running down his forearm. He was wearing a white T-shirt, blue jeans and a red shirt carried over his shoulder. Police described the second suspect as a black male, late 20s to early 30s and wearing a black T-shirt and cargo-style shorts.

The complex of two-story apartment buildings was searched by police officers the night of the attempted carjack, but the suspects were not located.

“I think my officers did an outstanding job last night in making sure the area and residents were safe,” LeTellier said.

The case remains under investigation. Anyone with information on the crime is asked to call Hightstwon Police at (609) 448-1234.
